LQFP 10X10-64L package(exposed pad up)
AW85601 is a digital input 4 channel automotive Class D audio amplifier with I2C control that delivers up to 80W of power at 25V power with 4Ω load and up to 10% THD+N, designed for high-performance LC feedback architecture of automotive audio and video products. The output noise of the amplifier is as low as 11μV to achieve extremely high signal-to-noise ratio, and the full power range output distortion is not affected by the nonlinearity of LC devices, achieving an excellent level. The output switching frequency can reach up to 2.1MHz, and the extremely high working frequency can eliminates the AM-band interference and reduces output filter size and cost. AW85601 support spread spectrum to enhance EMI performance.
AW85601 supports all AC and DC diagnostic requirements to adapt to all diagnostic scenarios. The device uses a compact and lightweight LQFP 10X10-64L package(exposed pad up) for better use by customers in multi-channel power amplifier design.
